Patented Apr. 15, 1930 JOHN' T. COX, OF BERLN, NEVI HAMPSHIRE, ASSIGNOR TO BROWN COMPANY, 0F BERLIN, NEW HAMPSHIRE, A CORPORATLIQN OF MAINE FLAKE-FORMENG METHOD Application filed May 22, 1926. Serial No. 110,840.

This invention relates to a method and journaled in suitable bearings as 10 carried mechanism for forming a ilaked food from by a machine frame 11. Outwardly of its dough and while not restricted to such use bearings 10 each of the trunnions 7 has keyed has been more particularly designed for the thereto a gear l2, the gears l2 of the two manufacture of a food product made from trunnions 7 intermeshing as shown in Figure 55 peanuts. Such a product may be made by 1. Apinion 13 meshing with one of the gears crushing peanutmeats with their brown ll is carried by a transversely arranged shaft skins, removing the oil as by extraction with 14 to which also is fixed a belt pulley l'by a suitable solvent as naphtha or ether, rewhich the shaft 14 may be driven thus to iinmoving the brown skins as by passing the part rotation in opposite directions to the 5e dry extracted meats past an exhaust nozzle, rolls 2 so as to feed the dough coming from reducing the residue to flour and then forrnthe hopper l through the nip between them. ing the liour into a dough with water and rl`heY dough in a relatively sticky condition any other desired ingredients as in a dough passing through the nip between the rolls is L5 mixer. This dough is then subjected to the pressed out into general sheet form, but .'55

The rolls 2 should be rotated slowly enough so that the dough is sufficiently dried by the time it reaches the doctors as to come away from the roll surfaces easily. The doctors 30 are held up against the peripheries of the rolls 2 and for this purpose, they are shown as attached to the inner ends of levers 35 pivoted at 36 to the frame 11 and having portions 37 extending outwardly of the pivot points suliciently to overbalance the'doctors and hold them yieldingly against the roll surfaces.

In Figure 3 is shown the manner in which the abutting surfaces ofthe rolls come together so that the mating ribs 3 thereon define sco-re lines, as shown in Figure 4; at 38, which so weaken the layers of dough adhering to these rolls that when they reach the doctors 30 the layers break off along the score lines in flakes as hereinbefore described.

In order to limit the width of the sheet of the sheet of dough, stripping the dried dough from said surfaces whereby it breaks apart substantially along the lines of indentation forming flakes, and then baking the flakes.

dough passing between the rolls to the lengths Y of these rolls, means are provided for closing ofi the ends of the nip through which the dough asses. As shown best in Figure '6, each o? these means comprises a plate 4() which is held by springs 41 surrounding guide pins 42 against the adjacent ends of the rolls and bridging the nip therebetween. These guide ins 42 for each plate slidably engage in per orations in a bracket 43 fixed to the upper member 44 of the frame 11.

Thesheets of dough, reduced to lake form, and deposited'on the belt 3l are passed into the oven 32 as hereinbefore described, and from this belt Slithey pass in succession to other belts 50 and 5l positioned within the oven, these belts acting to maintain the flakes in the Oven for a su'liicient length of time to properly cook them. The oven may be heated in any suitable way as by the burning oiz suitable fuelV y or by electric heating units placed beneath the upper stretches of the belts, and preferably the oven is maintained at a temperature sufficiently high to effect a quick coo-king and toasting of the dough so as to make it crisp and tender.

The various belts are preferablly made ci material such as wire gauze which will not be damaged by the heat and which will permit n
